Find the median values, mode values, and mean values among those who responded to both survey questions.
One student who initially chose to not respond now decides to respond. The median values for both variables stay the same. Find all possible values for the # hours of TV and # hours of HW that this student engaged in.
Find the median value of HW hours for those who watch less than 2 hours of TV.
In a separate study in New York, researchers find that the HW hours and TV hours are related in the following equation where H measures homework time in hours and T measures TV time in hours:
H(T)=-T2+4T+6. A mother in New York wants her child to complete 3 hours of HW per night. How many hours of TV watched would correspond with this, on the average?
